Just loaded F15C (love the boot screen by the way) and TP Gov.
* I am in the middle of a dead zone for data, running about 96k avg and PreCentral is always dead laggy loading under this solution. FWIW, PC snapped in very quickly after the update, and allowed me to scroll page while it was finishing the page load - a major breakthrough.
* Launcher is very snappy, smooth and WEB has never opened so quickly, bookmarks slider extremely responsive.
I will know more about battery tomorrow as I tend to stay charging overnight and untethered during the day. And I'm on this thing ALL day.
Update from home with broadband speeds:
I had not moved the gov from 1.5 to 1.7, I now have.
Browser competes with Chrome for speed. Very responsive.
